Note that the lookup in question is "MX", not "A". This means that
the message has a recipient address of "localp...@mx31.harte-lyne.ca",
rather than "localp...@harte-lyne.ca".
While harte-lyne.ca has working MX records, and the "A" record of
"mx31" resolves just fine, there are issues with *MX* lookups for
"mx31.harte-lyne.ca".
